veloping a uniform product and in advertising and marketing it. 

 In addition to apples and other fruits excellent yields are obtained 

 from alfalfa, cereals, and vegetables. Indian corn is successful 

 here; in 1914, 7,500 acres of this crop yielded an average of about 

 50 bushels per acre. 



SHOSHONE PROJECT, WYOMING. 



In Wyoming the Shoshone River is being utilized to develop a 

 project of 150,000 acres. In the canyon above Cody has been built 

 the Shoshone Dam, a rubble concrete arch 328 feet high and 200 feet 

 along the crest. This was the highest dam in the world when con- 

 structed, but has since been exceeded by the Arrowrock Dam, also 

 built by the Reclamation Service. Eight miles below Cody a diver- 

 sion dam turns the stored water into Corbett Tunnel, which delivers 

 to the main canal. Recent work has extended the distribution 

 system to reach 41,000 acres. Slightly over half of this is now being 

 irrigated so that the canal system is constructed well ahead of the 

 farming development. Agriculturally the project is essentially a 

 hay and grain producer, with small tracts devoted to vegetables and 

 garden truck. Alfalfa is the principal crop, exceeding all others 

 together in planted area and value of product. 



SUMMARY. 



Under the reclamation act of June, 1902, with later amendments, 

 the work of redeeming our arid lands has gone steadily forward to 

 the point where 23 projects or units have been completed so that the 

 problems of construction have been succeeded by those of oper- 

 ating the works for agricultural production. A million and a half 

 acres can now be supplied with water through the Government 

 systems, and half of this area is actually ]Droducing crops totaling 

 nearly $20,000,000 in yearly value. In effect a State has been added 

 to the Nation in that the annual production from the irrigated lands 

 already exceeds that of a number of the smaller States.
